"We seriously believe that the phenomenon of terrorism, takfirism and extremism is targeting everyone in this region and therefore we believe that a common threat can only be confronted through shared efforts," said Zarif at a press conference with his Lebanese counterpart Adnan Mansour.

For his part, Mansour said the meeting with Zarif tackled "the issue of terrorism that is rocking the region, which is a result of the Syrian conflict."

The Iranian foreign minister hoped "all the bilateral agreements signed (between Lebanon and Iran) in the past will be implemented, especially in light of the new global circumstances stripped of many obstacles preventing their realization."

Zarif arrived in Lebanon Sunday on a regional tour that includes stops in Syria, Jordan and Iraq. He has held talks with Lebanese military party Hezbollah's leader Sayyed Hassan Nasrallah and met with Lebanese President Michel Suleiman.
